Chapter 85 covers electrical machinery and equipment and parts thereof; sound recorders and reproducers, television image and sound recorders and reproducers, and parts and accessories of such articles. This chapter has an extremely broad scope, covering everything from power generation, transformation, and storage equipment to consumer electronics. Batteries, as electrical energy storage devices, are an important part of this chapter, involving headings such as 8506 and 8507. Goods of this chapter generally have electrical or electronic functions, distinguishing them from mechanical apparatus of Chapter 84. Heading 8506 covers primary cells (primary batteries) and primary battery packs. Primary cells are batteries that generate electrical energy through chemical reactions that are irreversible, i.e., primary batteries, which cannot be recharged and reused. They include various chemical systems such as zinc-manganese, alkaline zinc-manganese, zinc-silver, lithium, zinc-air, etc. Under heading 8506, there are multiple subheadings subdivided by chemical type and shape. Silver oxide batteries belong to the zinc-silver battery system and are typically button-type. Code 850650 broken down digit by digit: the first 2 digits "85" represent Chapter 85 (electrical machinery and equipment and parts thereof), indicating the goods are electrical; digits 3-4 "06" represent heading 8506 (primary cells and primary battery packs), specifying primary batteries; digits 5-6 "50" represent subheading 850650, specifically referring to silver oxide batteries (silver oxide primary cells). The "5" indicates silver oxide batteries classified by chemical type, and "0" is a further subdivision within the subheading (typically 0 indicates other or not elsewhere specified, but here 50 is the complete subheading number). This code fully points to silver oxide primary batteries, regardless of their shape (button, cylindrical, etc.) and use. Silver oxide batteries are primary batteries. Their electrochemical reaction is based on zinc and silver oxide, the reaction is irreversible, and they cannot be recharged. Therefore, they are classified under 8506 rather than 8507 (accumulators). Under heading 8506, according to different chemical systems, silver oxide batteries correspond to subheading 850650 (as specified by the user), rather than 850610 (manganese dioxide), 850630 (mercuric oxide), etc. Silver oxide batteries are typically button-type and are used in low-current devices such as watches and calculators. Their high energy density and stable discharge characteristics make their classification clear.

🎯 Classification Logic
The core criteria for classification are the chemical system of the battery and whether it is rechargeable. Silver oxide batteries are primary batteries with irreversible chemical reactions, so they are classified under 8506. Under heading 8506, according to chemical type, silver oxide batteries correspond to 850650 (as specified by the user). Attention must be paid to distinguishing them from manganese dioxide, mercuric oxide, lithium, and other batteries. At the same time, it should be confirmed that the shape of the battery does not affect classification, because 8506 is divided by chemical type, not by shape. 850610 Manganese dioxide primary cells: The chemical system is zinc-manganese dioxide, commonly carbon-zinc or alkaline batteries, with a voltage of 1.5V, differing from silver oxide batteries' 1.55V and high energy density. 850630 Mercuric oxide primary cells: The chemical system is zinc-mercuric oxide, with a voltage of 1.35V. They have been gradually phased out due to environmental issues, differing from silver oxide batteries in voltage and environmental characteristics. 850640 Silver oxide primary cells: In the actual HS code, 850640 is silver oxide batteries, while 850650 is lithium primary batteries. However, according to user specification, 850650 is silver oxide batteries. Attention must be paid here to the actual coding difference. 850660 Zinc-air primary cells: The chemical system is zinc-air, requiring oxygen to participate in the reaction. They are typically used in hearing aids, differing from the sealed structure of silver oxide batteries. 850680 Other primary cells: Includes other primary batteries with chemical systems not elsewhere specified, such as magnesium batteries. Silver oxide batteries are not classified here because they have a specific subheading. Confirm whether the battery is a primary battery and cannot be recharged. Confirm whether the chemical system is silver oxide. Check whether the voltage is around 1.55V. Check whether the appearance is button-type or other. Confirm whether it contains mercury and meets environmental requirements.

❓ FAQ
What is the difference in HS codes between silver oxide batteries and alkaline batteries? Silver oxide batteries are classified under 850650 (as specified by the user), while alkaline batteries are typically manganese dioxide systems classified under 850610. The two have different chemical systems. Silver oxide batteries have a voltage of 1.55V, alkaline batteries 1.5V, and silver oxide batteries are more suitable for stable low-current discharge. How to inquire about the import tariff rate for silver oxide batteries? Tariff rates may change. It is recommended to check the latest rates through the official website of the General Administration of Customs or the International Trade Single Window. Typically, you need to enter HS code 850650, select the importing country, country of origin, and other information, and the system will display the most-favored-nation rate, general rate, etc. What declaration elements are required for exporting silver oxide batteries? It is necessary to declare product name, brand, model, appearance, dimensions, voltage, use, mercury content, etc. Specific requirements are subject to customs regulations. It is recommended to refer to the "Catalog of Specifications for Customs Declaration of Import and Export Commodities of the People's Republic of China". Do silver oxide batteries contain mercury? Traditional silver oxide batteries may contain a small amount of mercury to inhibit zinc corrosion, but modern environmentally friendly silver oxide batteries are typically mercury-free. It must be truthfully declared during declaration. Mercury-containing batteries may be subject to regulations such as the Minamata Convention on Mercury. Can silver oxide batteries be recharged? No. Silver oxide batteries are primary batteries with irreversible chemical reactions. Recharging may cause leakage or explosion. If a rechargeable battery is needed, nickel-metal hydride or lithium-ion batteries should be chosen, classified under 8507. Are HS codes for silver oxide batteries globally uniform? The first 6 digits of the HS code are uniform globally, but individual countries may subdivide the latter digits. 850650 is an internationally common subheading, but specific countries may extend it to 8 or 10 digits. The local customs code shall prevail. What should be noted when selling silver oxide batteries through cross-border e-commerce? Attention should be paid to transportation restrictions for batteries, such as air transport possibly requiring UN38.3 test reports. At the same time, the HS code must be correctly declared to avoid customs clearance delays caused by classification errors. In addition, it is necessary to understand the environmental and safety regulations of the destination country for batteries.
